Rotational Molding

Rotational Molding, also known as RotoMolding, is a plastics molding technology which is ideal for making hollow articles. It is a casting technic but unlike most other plastics processes there is no pressure involved. Molds for the process are relatively inexpensive as they do not have to withstand pressure and therefore relatively short production runs can be made very economical-ly. RotoMolding is used to make a very diverse range of products. The process offers the product designer exceptional freedom as just about any shape can be produced. There is almost no limit to the size of moldings and there are literally thousands of applications. The concept of rotational molding is very simple. A plastic material, normally in powder form is placed into a hollow mold, usually made from cast aluminum or fabricated from sheet steel. The mold is closed and rotated slowly on two axis. The mold is then heated in an oven whilst rotating and the polymer gradually melts and ‘lays-up' on the inside of the mold. Once the polymer powder has fully melted the mold is moved to a cooling station and cooled usually with air and sometimes a fine mist of wa-ter. As the mold cools the part solidifies. When the material has finally cooled sufficiently to re-lease away from the mold surface the process is stopped and the product is taken out of the mold.
